Didier Barrouillet and a cure for esca? – Wine Terroirs

Following on from the end of my last post with some small, high-quality Loire producers deserting appellation contrôlée because of its perceived failure to incorporate environmental concerns within its rules, Bertrand Celce has another excellent article on his blog – Wine Terroirs. It's an interview with Didier Barrouillet of the Clos Roche Blanche. Didier explains how he uses plants to build micro-diversity in his vineyards and micro-bacteria in his soils. He claims success against esca, which is a grave threat to the Sauvignon Blanc vines. Didier is convinced that there is a link between esca and the widespread use of Roundup that in time leaches down to a vine's roots killing the micro-bacterial life that can protect a vine. Typically the INRA (France's vine research institute) considers Didier to be a 'lunatic'!

... and this is sane!?

I was aware, and Bertrand's article confirms this, that Didier, like Claude Papin and others, has grave doubts about turning the soil over and thus destroying its profile.

Didier is nearing retirement – he and Catherine Roussel have reduced the size of Le Clos Roche Blanche to nine hectares – and he intends to concentrate on his work in the vineyard. It would be good to see Didier set up a website or a blog to spread his ideas and findings to a wider audience.

See also here comments on Bertrand's article on the Clos du Porteau blog – Aynard is very concerned by the threat that esca poses to his Sauvignon Blanc.

Also a very brief report here on the Porteau blog on Esprit Vif held yesterday at Château des Couldraies in Saint-Georges-sur-Cher. It appears to have been a success.

(This post was originally tacked onto the my previous post but I think it makes more sense to post this separately.)
